Thanks to this poster at a Duane Reade store at the corner of Park Avenue and 56th Street in New York, customers know that they can pick up their prescriptions at any of Walgreens’ more than 7,000 stores in all 50 states.

One disadvantage to having a prescription at a locally owned pharmacy is that it can complicate things if one needs a prescription while in another city or state, but a large chain with stores across the country doesn’t have those limitations.
